PREFACE. 

The intention of the author of this book is to put into the 
hands of students and farmers a work which is thoroughly 
practical. The contents of soil, elements, materials and acids 
are clearly defined. The home mixing of fertilizers depends 
upon our knowledge of compounding fertilizer materials for 
the need of plants. Home mixing enables the farmer to 
buy fertilizers for less money and to supply different plants 
with food as they need it. 

It is poor economy to use a fertilizer which is low in 
analysis and one which contains an acid not neutralized. All 
farmers should learn to remove the acid conditions of their 
soils and keep them in a feebly alkaline state by using lime. 

Lime is used to counteract acid and to destroy harmful 
bacteria. Nitrate-forming bacteria cannot thrive successfully 
in acid soils. Well drained soils, supplied with humus, always 
produce good crops. 

The acre formulas in this book may be used at different 
periods during the cultivation of the crop or may be used 
broadcast. 

The tonnage formulas show the analysis, cost and appli- 
cation of same. 

Fertilizer materials for making fertilizers are subject to 
fluctuate. The cost of a ton of fertilizer named in this book 
means cash, delivered by the dealer. Farmers should grow 
less cotton and tobacco and grow more food products. Stock 
your farm with thoroughbred animals, grow legume crops 
and pay cash for your fertilizers which contain phosphorous 

and potash.

(Q) How does lime affect sandy soils ? 

(A) Lime applied to sandy soils makes them stiff soils. If 
applied to such soils is of little value if they contain no 
decayed vegetable or mineral matter. 

(Q) How does lime affect clay or stiff soils? 

(A) Lime applied to clay or stiff soils makes them mellow 
and liberates the potash in them. 

(Q) What forms of acid soils will lime counteract? 

(A) Lime will counteract all forms of acid soils, such as 
ulmic, humic and crenic. 

(Q) What causes ulmic, humic and crenic forms of acid 
soils ? 

(A) Ulmic, humic and crenic forms of acid soils are caused 
by decayed vegetable matter in the soil and the use of fer- 
tilizers that contain an acid not neutralized. Improper drain- 
age and tillage produce sour soils.

Lesson 19. 

(Q) What kind of soil bacteria are destroyed by the use of 
lime? 

(A) Harmful bacteria are destroyed by the use of lime. 

(Q) How can the farmer tell whether or not his soils con- 
tain acid or are sour? 

(A) The farmer can tell whether or not his soils contain 
acid by using an acid tester. The acid tester determines 
whether or not his soils contain acid and it also registers the 
number of pounds of lime required per acre to take out the 
acid. 
AQ) When should lime be applied? 

(A) Best to apply it in the fall, if possible. Always broad- 
cast lime and harrow it in. 

(Q) When is the best time to apply lime for green crops 
plowed under? 



22 Chemistry Applied to Peacjtioal^Farming 

(A) Plow under the green crops, then disk thoroughly, 
broadcasting the lime before disking. 

(Q) Can corn or cotton grow on sour soils that would 
require 2,000 pounds of lime per acre to counteract the acid? 

(A) Yes, corn and cotton will grow on such soils, but 
would make far better crops, if the soil was sweet, on less 
fertilizer. 

(Q) Why will any crop produce more on a sweet soil than 
a sour soil ? 

(A) All sweet soils, well drained and well tilled, containing 
an abundance of humus, are well supplied with nitrate- 
forming bacteria. Such soils always produce good crops. 
Nitrate-forming bacteria can not thrive successfully in a sour 
soil. 

ACIDS. 

Lesson 29. 

(Q) What is phosphoric acid ? 

(A) Phosphoric acid is a plant food obtained from the 
phosphorous of various substances or materials by some chem- 
ical combination. 

(Q) Can you name some fertilizer materials that contain 
phosphorous ? 

(A) Cotton seed meal, fish guano, tankage, bone meal, cal- 
cium phosphate and castor pomace contain phosphorous. 

(Q) How is the phosphorous in cotton seed meal, fish 
guano, tankage, castor pomace, calcium phosphate and all 
vegetable matter naturally converted into phosphoric acid? 

(A) The phosphorous in all these materials or elements 
is naturally converted into phosphoric acid by the chemical 
action of nitrification through nitric acid, which is obtained 
from some source of ammonia or nitrogen. 

(Q) How does the phosphorous in the phosphate rock be- 
come available artificially? 

(A) It becomes available artificially by the treatment of 
sulphuric acid. 

(Q) What is sulphuric acid? 



AND Home Mixing Feetilizees 23 

(A) Sulphuric acid is a compound of sulphur, oxygen and 
hydrogen. 

(Q) Wliat is nitric acid? 

(A) Nitric acid is a compound of nitrogen and oxygen. It 
is the final product which is obtained by chemically releasing 
ammonia or nitrogen. 

ACIDS. 

Lesson 21. 

(Q) How is nitric acid naturally obtained? 

(A) Nitric acid is naturally found in compost heaps and 
in all soils where animal and vegetable matter are undergoing 
decay in contact with the air. 

(Q) What happens when nitric acid comes in contact with 
soda, lime, potash, magnesia, etc. ? 

(A) When nitric acid comes in contact with potash it 
forms nitrate of potash. When it comes in contact with lime 
it forms nitrate of lime, etc. 

(Q) What is ulmic acid? 

(A) Ulmic acid is a compound of carbon, hydrogen and 
oxygen. It combines with lime, magnesia, alumina and oxide 
of iron. It is produced by the decay of vegetable matter in 
the soil. It requires 2,500 times its weight of water to 
dissolve it. 

(Q) What is humic acid? 

(A) Humic acid is a compound of carbon, hydrogen and 
oxygen. It is produced by the sour forms of humus which 
is obtained from decayed matter in the soil. It combines with 
lime, magnesia and oxide of iron. 

(Q) ^\Tiat is crenic acid? 

(A) Cienic acid is a form of acid formed in the soil 
during the decay of green vegetable matter. It is distin- 
guished from ulmic and humic forms of acid by containing 
nitrogen as an essential element. It forms a compound with 
lime and is soluble in water. 

(Q) What is carbonic acid? 

(A) Carbonic acid is a compound of carbon and oxygen.

BACTERIA. 

Lesson 22. 

(Q) What are soil bacteria? 

(A) Soil bacteria are microscopic germs, organisms, plants 
or bacteria that live in diflterent conditions of soil. 

(Q) How many kinds of soil bacteria are there that affect 
the farmer in the production of plants? 

(A) There are three kinds of soil bacteria that affect the 
farmer in the production of plants. They are as follows : 
(1) harmful bacteria, (2) nitrate-forming bacteria, (3) 
legume bacteria. 

(Q) What are harmful bacteria? 

(A) Harmful bacteria are bacteria that hold sway in acid 
or sour soils. They destroy legume and nitrate-forming 
bacteria. 

(Q) Why are they called harmful bacteria? 

(A) They are called harmful bacteria because they do us 
harm. They are our greatest soil enemies. 

(Q) How are harmful bacteria destroyed? 

(A) When lime is applied to acid or sour soils the acid 
combines with the lime and when this combination takes 
place the harmful bacteria perish. 

(Q) What are nitrate-forming bacteria? 

(A) Nitrate-forming bacteria are bacteria that produce 
nitric acid by the process of nitrification in the soil. 

BACTERIA. 

Lesson 23. 

(Q) What elements or properties carry nitrate-forming 
bacteria ? 

(A) All properties or materials containing ammonia or 
nitrogen carry nitrate-forming bacteria. All decaying animal 
and vegetable matter contain nitrate-forming bacteria. 

(Q) Of what value are nitrate-forming bacteria to the 
farmer ? 

(A) Mtrate-forming bacteria make nitric acid and nitric 
acid has the controlling power in the soil to make the dis- 
tribution of all other properties for the use of plants. 



AND Home Mixing Feetilizers 25 

(Q) In what kind of soils can nitrate-forming bacteria 
live? 

(A) Nitrate-forming bacteria cannot thrive successful!}^ in 
an acid or sour soil. Good drainage and tillage encourage the 
growth of nitrate-forming bacteria. 

(Q) How can the farmer keep a good supply of nitrate- 
forming bacteria in his soil ? 

(A) Every farmer can keep a good supply of nitrate- 
forming bacteria by keeping a full supply of humus in the 
soil. Grow and turn under legume crops for cheap humus. 

(Q) What are legume bacteria? 

(A) Legume bacteria are very small plants that bore into 
the roots of legume plants. 

(Q) How do legume bacteria live? 

(A) They live on carbohydrates and nitrogen gas. 

BACTERIA. 

Lesson 24. 

(Q) How do legume bacteria make nitrogen? 
(A) They digest the food they eat and it is deposited in 
the nodules on the roots of the plants in the form of a nitrate. 
(Q) What is the form of the nitrate in these nodules? 

(A) The nitrogen in these nodules is in the form of 
albumoid. 

(Q) What per cent, of these nodules is nitrogen ? 

(A) These nodules are 8 per cent, nitrogen. 

(Q) When does the nitrogen in these nodules become 
available ? 

(A) The nitrogen in these nodules becomes available when 
the nodules decay. 

(Q) How are legmme bacteria cultured? 

(A) Legume bacteria are cultured by selecting choice forms 
of the bacteria and breeding the culture. 

( Q ) Does each legume plant carry its own kind of bacteria ? 
(A) Each legume plant carries its own kind of bacteria. 



26 Chemistry Applied to Practical Farming 

(Q) Can legume bacteria live in acid soils? 

(A) Legume bacteria cannot thrive successfully in acid or 
sour soils. For this reason we lime soils for legume crops. 

(Q) Where are cultures of bacteria produced? 

(A) These cultures are bred in the laboratory. 

(Q) How does the farmer inoculate his seeds of legume 
plants with cultured bacteria? 

(A) All farmers who wish success for inoculation of the 
seeds of legume plants, can use Farmogerm. 

HOME MIXING FERTILIZERS. 

Lesson 25. 

(Q) What is home-mixing fertilizers? 

(A) Home-mixing fertilizers is buying materials and com- 
pounding them in the proper proportion for the need of 
plants. 

(Q) How can you tell the number of pounds of acid phos- 
phate or Thomas phosphate that are required to make a ton 
of fertilizer that will analyze 8 per cent, phosphoric acid? 

(A) Multiply the number of hundred weight in a ton by 
the per cent, required, annex two ciphers and divide by the 
per cent, of the material used. Thus: 20X8=160.00-^16= 
1,000 pounds. 

(Q) How can you tell the number of pounds of nitrate of 
soda and cotton seed meal that are required to make a ton 
of fertilizer analyzing 4 per cent, ammonia? 

(A) Multiply the number of hundred weight in a ton by 
the per cent, required, annex two ciphers and divide by the 
per cent, of the material used if you are using only one 
material. Two hundred pounds of nitrate of soda furnish 
36 pounds of ammonia. Eighty pounds of ammonia are 
required to make the ton analyzing 4 per cent. Eighty 
pounds minus 36 pounds equal 44 pounds more, which we 
get from cotton seed meal, annex two ciphers to the 44 
and divide by 8 the per cent, of the cotton seed meal, and 
we have 550 pounds of cotton seed meal and 200 pounds of 
nitrate of soda which, when combined, make the ton analyzing 
4 per cent, ammonia. 



AND Home Mixing Feetilizers 27 

HOME MIXING FERTILIZERS. 

Lesson 26. 

(Q) How can you tell the number of pounds of muriate 
of potash that are required to make a ton of fertilizer 
analyzing 10 per cent, potash? 

(A) Multiply the number of hundred weight in a ton by 
the per cent, required, annex two ciphers and divide by the 
per cent, of the material used. 

Thus: 20X10=200.00-^-50=400 pounds. 

(Q) How can you tell the number of pounds of kainit that 
are required to make a ton of fertilizer analyzing 2 per cent, 
potash ? 

(A) Multiply the number of hundred weight in a ton by 
the per cent, required, annex two ciphers and divide by the 
per cent, of the material used. 

Thus : 20X2=40.00-^-12=333 1-3 pounds. 

(Q) How many pounds of dried blood are required to make 
a ton of fertilizer analyzing 4 per cent, ammonia? 

(A) Multiply the number of hundred weight in a ton by 
the per cent, required, annex two ciphers and divide by the 
per cent, of the material used. 

Thus: 20X4=80.00-^16=500 pounds. 

(Q) Should the ammonia in a ton of fertilizer always be 
secured from one material in making a ton of fertilizer? 

(A) The best results are always obtained when we get 
ammonia from more than one material. Nitrate of soda, 
tankage, fish guano, dried blood and cotton seed meal are safe 
sources for ammonia.

HOME MIXING FERTILIZERS. 

Lesson 27. 

(Q) What are the necessary tools or implements to use in 
home mixing? 

(A) Use a box 16x8 feet, 10 inches deep. Pour your 
materials into the box in layers. If you use nitrate of soda, 
take it first and carefully crush all lumps in bottom of box. 
Then pour in separately, in layers, the other materials and use 
hoe, carrying back and fourth twice. Then use shovel and 
place back into same bags. 

(Q) Will it be necessary to use dirt or any material as a 
filler to make the number of pounds in the ton weight exactly 
2,000 pounds? 

(A) You need no dirt or filler of any kind. The materials 
you use contain all the filler you need. There is no business 
in buying a fertilizer containing a filler such as worthless dirt. 

(Q) How much can a farmer save by doing his own 
mixing ? 

(A) Any farmer can save from $3.00 to $6.00 on each ton 
he mixes. 

(Q) Is there any other advantage in home mixing? 

(A) The farmer who does his own mixing dictates for 
himself and mixes the materials to suit the demand of his 
plants.

This formula is for land that produces all vines and no peas. The 
cow pea is a legume plant and like clovers connot thrive well in acid 
or sour soils. Test your soils for acidity and you can tell whether or 
not Thomas Phosphate will furnish all the lime you need. Take the 
acid out of your s©il, fertilize it, inoculate your seed peas with Farmo- 
germ and you will make peas and a crop of nodules.
